The Great Western Railway purchased two diesel shunters, and ordered a further seven immediately prior to Nationalisation, which were delivered to British Rail in 1948–49. The two shunters used by the GWR were numbered 1 and 2, while a series commencing at 501 was planned for the new locomotives ordered in the 1940s. British Rail renumbered both its inherited and new locomotives in a series commencing from 15100.

This locomotive was built by Fowler in 1933 and was used at Swindon Works. It was an 0-4-0 diesel mechanical shunter with a 70 hp (52 kW) engine, 3 ft (0.914 m) diameter wheels and a wheelbase of 4 ft 6 in (1.37 m). It was very similar to the London, Midland and Scottish Railway's (LMS) departmental locomotive number 2, which was built a couple of years later. It was withdrawn in 1940 and sold to the Ministry of Supply.^[1][2]

This locomotive was built by Hawthorn Leslie in 1936 and allocated to Swindon. It was a 0-6-0 diesel electric shunter, very similar to the LMS 7069 class (later British Rail Class D3/6), and with a close family resemblance to the Southern Railway Maunsell 350 hp DMS (SR 1 - SR3). It was renumbered 15100 by British Rail in 1948, withdrawn in 1965 and scrapped in early 1966.^[1]
